I have a USB audiophile device that uses draws plenty of power from the USB port and is vital for my primary use of the tablet. Is there a way to have an special OTG cable that prevents the tablet’s battery charge to empty too fast? I have one with 2 USB2.0 connector for devices and 1-port that supposedly is used to connect the charging cable so the tablet doesn’t discharge or does discharge at a supposedly much slower rate, but when using this OTG cable with the charger, Windows doesn’t acknowledge it and functions as there is normal battery discharge.

I think you need something like this: http://www.amazon.com/USB-OTG-Power-Y-Cable/dp/B00H3J0L0A

Maybe is there a USB3.0 OTG cable that let me connect my device and keep the charging port free so I can connect to the charger? Which one do you recommend?

Yes, i’ve been using one i bought at a local Hama store: https://www.hama.com/00015709/hama-usb-30-otg-adapter-cable-micro-plug-a-socket-black-015-m?bySearch=usb%203%20otg#

There exsists also usb 3 OTG Y cable: http://www.dx.com/p/usb-3-0-female-to-micro-usb-3-0-otg-cable-w-adapter-black-20cm-289081#.VytQUx-6y1J

Thanks jetfin!

The 1st link shown one cable very similar to the one I already have (mine has 2 usb2.0 ports) but in the reviews some people describe the same problem that it does not charge. Is this a cable you have tried? I don’t wanna throw away the money if I already have a cable with the same problem.

 

The links for the USB3.0 look interesting specially the 1st one (although it doesn’t have a way to buy it). Also have you tried these cables?

 

You or anyone knows if the USB3.0 on the tablet provides power? I think I saw in the past some comment somewhere saying the USB3.0 port had some kind of power problem?

 

Thanks!

I think this device looks appropriate? (though costly)

Any opinions?

Forget about the last one. Onw reviewer says “While using the OTG function, the station can’t charge device”

I’ve only been using the regular usb 3 otg (HAMA).

The usb 3 port on this device supplies 5v power

USB 3.0 port on this device is rather dissapointing if you want to power some “hungry” devices. My measurements indicates that voltage drop to 4.85V with just 0.25A current drawn. I do not see any possibility to draw 0.9A (as per USB 3.0 specification) from this port. In such case powered USB Hub is required.

Thanks!

 

For the input! That’s what I figured, it seems if I want to use that device which is pretty hungry, I’m gonna have to keep the charger connected, a USB3.0 cable as a host which connects to a powered HUB.

 

Any recommendations for a confirmed good quality charging HUB?
